Definitions

  • This invention relates to milling cutters, and particularly to cutters for milling T-slots, and to indexable replaceable cutting inserts therefor.
  • T-Slot milling cutters having replaceable hard metal cutting inserts of the tangentially-mounted or “on edge” type, i.e., in which the rake face is an edge surface of the insert, as distinguished from radially-mounted or blade type inserts which present a major surface to the workpiece as a rake face, are subject to both axial and rotational dislodgement by the cutting force reaction.
  • the opposite and alternative rake and positioning edge surfaces of the insert of the invention present a generally convex configuration as a result of being divided into three facets, a central facet which lies in a plane parallel to the rotational axis of the cutter body when mounted in rake position, and two flanking facets which recede diagonally and symmetrically from the central facet.
  • the flanking facets of the rearwardly facing edge of the insert are received as a wedge by mating angularly disposed facets of the rear wall of the insert pocket, the central facet of the insert edge surface being received within a depression in the rear wall of the pocket without engaging the boundaries thereof.
  • the rotative position of the insert is thus determined entirely by the wedging engagement of the respective angularly-disposed flanking facets of the insert and the pocket.
  • the generally convex configuration of the three facets of the edge surface enhances the cutting action by introducing a further slashing element to that action.
  • FIG. 1 is an elevational view of the T-slot miller of the invention
  • FIG. 2 is a top or end view of the cutting head of the tool
  • FIG. 3 is a fragmentary elevational view of the cutter head proper rotated slightly from its position in FIG. 1;
  • FIG. 4 is a fragmentary top view of the cutter head corresponding orthographically to FIG. 3;
  • FIG. 5 is an enlarged fragmentary view of the cutter head showing the insert in place
  • FIG. 6 is an enlarged fragmentary view corresponding to FIG. 5 and with the near side cutting insert removed to show the detail of the insert seat;
  • FIG. 7 is an enlarged perspective view of the cutting insert of the invention, removed from the cutting head.
  • FIGS. 8, 9 , 10 , and 11 are orthographic projections of the cutting insert alone, displaying its several faces.
  • the majority of the length of the cutter body is taken by a gripping shank 17 having one or more flats 19 for rotary driving engagement by a tool holder.
  • the shank is necked down at the free end of the cutter to define a cutter head 21 which is milled to provide three insert pockets 23 and chip gullets 25 in the illustrated case.
  • the main seating surface 27 of the pocket is slightly offset from the parallel out-facing surface of the chip gullet, as best seen in FIG. 4 .
  • the profile of the cutter head 21 on a radial plane, and the slightly larger profile of the cutting path, are half-round, as the illustrated cutter was developed for machining retention slots for the gaskets of interfitting metal parts.
  • the cutting path profile, half-round in this case is however, irrelevant to the invention, which is applicable equally to T-slot millers of square or other profile.
  • the cutting insert 29 is of the tangentially-mounted “on edge” type, in which one or more of the lesser edge surfaces constitute the rake face 31 and provide the cutting edges 33 .
  • the cutting edges 33 extend radially and axially beyond the profile of the cutter head itself, FIGS. 3 and 5, simultaneously milling all surfaces of the slot, i.e., all surfaces disposed radially and axially from the cutter head. In the illustrated case, radially and axially disposed cutting edges become merged in the half-round profiles noted.
  • the insert pocket 23 milled in the cutter head comprises the aforementioned flat tangential seating surface 27 terminating rearwardly, relative to cutting direction, in an upstanding ledge 35 (FIG. 6 ), which serves as an abutment for the cutting insert 29 to receive the thrust of the cutting force reaction.
  • the insert 29 is secured in the pocket by a counter-sink headed screw 37 received in a countersunk through hole 38 in the insert 29 and a threaded hole 39 in the cutter head.
  • the hole 39 in the cutter head is directed at a slight angle to the seating surface 27 to enable the conical head of the screw 37 to thrust the insert endwise against the abutment ledge 35 of the pocket, the engaging surfaces of which are an important feature of the invention.
  • the engaging surfaces 41 of the abutment are two, which are inclined to one another symmetrically about a radial plane and separated by a central depression 43 .
  • the inclination of the engaging surfaces 41 of the abutment matches that of two cooperating surfaces 45 of the cutting insert.
  • their symmetrical inclination with respect to a radial plane renders their engagement mutually wedging to resist cutting force reaction tending to rotate the insert about its securing fastener 37 , a countersink-headed screw in the illustrated case.
  • Their inclination with respect to an axial plane is determined by the requirements of the cutting geometry, and may therefore vary with the diameter of the cutter.
  • the insert is bilaterally symmetrical about planes respectively parallel to the axis of the cutter body and perpendicular thereto, the latter to ensure the maintenance of the cutting profile in both indexable positions of the insert
  • the top, or radially outward surface 47 of the insert is essentially cylindrical, but may be slightly elliptically ovate, if precisely half-round projection of the cutting profile is required.
  • the bottom or radially inward, seating surface 49 of the insert is plane and oblong, differing from rectangular by the slight inclination of the abutment engaging surfaces 45 of the alternative faces, which intersect it (FIG. 8 ).
  • the opposing alternative rake faces diverge symmetrically from the seating surface 49 of the insert 29 at an angle determined by the cutting geometry, as before noted (FIG. 9 ).
  • Each rake face is itself divided symmetrically into three facets, namely, a central facet 51 and the two flanking receding facets 45 of size equal to each other, which diverge from the central facet 51 at the same inclination as the engaging surfaces of the abutment ledge 35 of the insert pocket.
  • the fastener hole in the insert is precisely centered at the intersection of both axes of the symmetry so that the securing screw 37 , while holding the insert against the seating surface 27 of the pocket, simultaneously urges the flanking surfaces 45 of the unused rake face into tight wedging engagement with the mating surfaces 41 of the abutment.
  • the insert When so engaged, the insert is secure against cutting forces reactions tending to dislodge it, even as they may become unbalanced axially of the cutter head due to unequal wear, and tend to rotate the insert about its retaining fastener.
  • the shank 17 of the cutter body is provided with an axial conduit 53 for cutting fluid, delivered under pressure from the machine spindle, the central conduit 53 dividing into three splayed lesser channels 55 , each opening to a port 57 at the insert pocket in front of the rake face of the insert.
  • the fluid delivered cools and lubricates the cutting site, and provides a flushing action to facilitate chip removal.
